B and Charles have spent the last few weeks making an igloo in the snow. Last weekend they finished it. Once they had hollowed the whole thing out, they added a couple of skylights using sledding disks.
When the excavation was complete, and since snow is every couple of days here this winter, B used a piece of cardboard and made a form around the opening and then used the snow blower to direct snow over it to fill it in and make a proper igloo opening.
Once this process was complete, B bedded down the floor inside with straw, and made an area for a small fire pit inside. I hope to take more pictures of the inside soon, but this happened to my camera due to some exuberant boys playing in the wrong area.
So, I'll post more pictures once we get that situation fixed. To give you an idea of the scale of the thing, Charles is on top and B is inside excavating here.
